Climate change is one of the most important issues to tackle this generation and possibly any generation in history. Bangladesh is likely to be one of the most vulnerable countries in the world to climate change. This paper discusses the possible impacts of climate change in Bangladesh through tropical cyclones, storm surges, coastal erosion and back water effect. Both qualitative and quantitative discussions are made on cyclone intensity increase for a sea surface temperature rise of 2 and 4°C. Different scenarios of storm surges under different climate change conditions are developed by using a numerical model of storm surges for ...view middle of the document...
The exposures to different risks get aggravated because of varying high population density, poverty level and concentration of economic activities in different parts of Bangladesh. Many projected climate change impacts including sea level rise, temperature increase, evapo-transpiration losses, enhanced monsoon precipitation and run-off, potentially reduced dry season precipitation and increase in cyclone intensity would in fact reinforce the baseline stresses like yearly flooding, river bank erosion, salinity intrusion etc. that already poses serious impediment to the economic development of Bangladesh. A Number of studies have established the consequences of climatic effect on Bangladesh and assessed adaptation practices, options, constraints and capacities. The country is already beset with many problems like high population density (120 million people living in an area of 144000 km2), shortage of land to accommodate the people, food security, human health, illiteracy, and so forth. The abovementioned types of disasters make the problems all the more complicated. In the foreseeable future, Bangladesh is likely to be one of the most vulnerable countries of the world in the event of climate change. The global warming due to the increase in greenhouse gas concentrations in the earth’s atmosphere and the consequent sea level rise (SLR) are going to add fuel to the fire. In the World Risk Index 2011, jointly conducted by United Nations University (UNU), Germany and the Institute of Environment and Human Security said that Bangladesh ranked sixth among countries that are most vulnerable to natural disasters, while second among the Asian countries. Most of the climate change impacts in Bangladesh are likely to come from the south —that is, the Bay of Bengal and the adjoining North Indian Ocean. These waters are the sources of tropical cyclones and storm surges, coastal erosion, monsoon wind, evaporation for monsoon rainfall, floods, and droughts. Considering these, the present paper concentrates on the following topics: tropical cyclones, storm surges, coastal erosion, back water effect on floods, increasing heat waves-drought, Salinity Intrusion and mental and physical health effects by Climate Change in Bangladesh.
